APPARATUS FOR WASHING CROCKERY Specification of Letters fatent.

Patented June 2 2, 1915.

Application filed October 18,1912. Serial No. 726,404.

To all whom it may concern Be it known that I, HENRY MUNRO PEARMAN, a subject of the King of Great Britain and Ireland, and resident of Oxford, county of Oxford, England, have invented certain new and useful Improvements in Apparatus for Washing Crockery, of which the following is a specification.

This invention relates to an improved apparatus for washing crockery and consists essentially of three chambers, the outer two of which are for washing purposes while the central chamber (the rinsing chamber) is provided with a wire basket and means for raising and lowering said basket when required from or into the boiling water within said central chamber, means further being provided for carrying away grease and floating pieces from the washing chamber and means for cleaning out the rinsing chamber.

The invention is illustrated by the accompanying sheets of drawings.

Figure 1 is a detail View hereinafter referred to; and, Fig. 2 is a longitudinal section.

Like letters of reference indicate corresponding parts. p

In carrying out the invention, the crockery is washed in the chambers a, a and then thrown into the wire basket I) located within the rinsing chamber 0, said chamber 0 being provided with boiling water kept at boiling point by steam from jet d.

In the embodiment of the invention shown in Fig. 2, a pivot bar 1 is employed extending transversely across the apparatus, which bar may be mounted in plain or ball bearings. Fixedly mounted on said bar and at each side thereof adjacent the interior side face of the apparatus is a quadrant member 2 preferably with a grooved edge, and to each quadrant is secured a hoisting wire 3 fixed to the topmost portion of said quadrants curved face by any convenient clamping device. The arrangement is such that each hoisting wire extends approximately vertically downward and 1s securedvto one corner of the wire basket carrier 4 hereinafter described; the wires thence continue, each on its respective side, down and around a loose pulley 5 mounted on the interior of the apparatus, and thence diagonally upward to the top of the apparatus over a second loose pulley 6. The wire then extends downwardly in approximately vertical dimotion and is secured to another corner of the wire basket carrier 4. Thus the carrier 4 issuspended by its four corners. The said carrier' is in the form of a framework of angle iron into which the wire basket I) and said carrier is adapted to easily travel by the provision of an inclined runner 7 projecting from each corner and snugly fitting the corner recesses of the apparatus. The wheels of the runners are desirably rounded off at their contacting edges, or may be otherwise shaped. Thus, in action, when the quadrants are oscillated up or down, the lifting wires are correspondingly operated to raise or lower the carrier and basket; and to operate the quadrants, the transverse spindle 1 is preferably provided at one or both extremities (which extend for this purpose through to the exterior of the apparatus) with an operating lever 8. This latter may be secured in its raised position, corresponding to the raised position of the basket, by means of a suitable stop, not shown. An overflow pipe a connects each washing chamber a with the rinsing chamber 0 so that the water created by the condenser steam may be carried away from said chamber c to the washing chambers a, thus keeping said chambers a supplied with water. Further, each washing chamber a is provided with a wide-mouthed overflow funnel a connected to the common drain pipe a to carry away all surface grease and floating pieces on the water, while maintaining a constant water level, to the manhole chamher (not shown) usually provided in large washup houses.

The basket I) is with a flap I) provided at the bottom which can be lifted to enable the chamber 0, when said basket is raised, to be cleaned, an outlet pipe closed by any suitable arrangement of plug, connecting said chamber 0 with the drain pipe a to enable the dirty water to be drawn off when required.

For the purpose of operating the pivot bar or shaft 1, the same is provided with a suitable handle a, and for holding the handle in position when the basket is raised any suitable arrangement of pawl and ratchet or equivalent dBVlCF may be used, such for instance, as shown in Fig. 1.

An apparatus constructed on the above lines is simple in working, very expeditious and effects a saving in linen inasmuch as no wiping is required, the crockery, when the basket is raised, draining dry, and, further, it also effects a saving of time Where a lar e quantity of crockery 1s in daily use.

aving now described my invention, What I claim as neW and desire to secure by Letters Patent of the United States is 1-- A hoisting device for receptacles comprising, in combination with the receptacle, a basket element arranged therein, means for operating said basket element including a shaft having journal bearings in the recep tacle, quadrants carried by the said shaft and having peripheral grooves, pulleys also mounted on the inner opposite sides of the receptacle and diagonally arranged, flexible basket supporting means attached to the quadrants and lower corners of the basket element and also passing around the diagonally arranged pulleys, and means for holding the basket in its elevated position.

In testimony whereof I have afiixed my signature in presence of two Witnesses.
